ImpOTANT pRECAUTIONS pRIOR TO INSTALLATION ANd USE

Intended Use

Skystream Hybrid 6TM is a wind and solar powered electricity generation system containing multiple integral AC power inverters. It is designed to supplement the electrical power provided by the local electric utility com-pany in residential and commercial applications by connecting directly to the user’s main AC utility panel. Skystream Hybrid 6TM may also be utilized to provide power with battery based residential electrical systems or utility grid connected systems with battery back-up.

Skystream Hybrid 6TM is designed to operate at sites with average wind speeds less than 19 mph (8.5 m/s), equivalent to International Electrotechnical Commission (IEC) Class II wind conditions. The installa-tion of Skystream Hybrid 6TM at sites with higher average wind speeds will accelerate component wear and require more frequent inspections for the wind turbine, tower, and solar tracking system and framework. There are no solar insolation constraints on locating Skystream Hybrid 6TM.

Unintended Use

Utilizing Skystream Hybrid 6TM for other than its intended purposes or with inappropriate equipment or modifying Skystream Hybrid 6TM is not autho-rized by Southwest Windpower and will void the warranty and may result in serious or fatal injury.

• Do not attempt to use power sources other than the wind or sun to power Skystream Hybrid 6TM, for example connecting pulleys or use as a water powered turbine.

IMPORTANT: Precautions listed here cannot address all the possible misuses of Skystream Hybrid 6TM. Please contact Southwest Windpower if you have any questions regarding the proper installation or use of Skystream Hybrid 6TM.

Skystream dealer

Installation personnel

Southwest Windpower strongly recommends professional installation of Skystream Hybrid 6TM. While Skystream is not difficult to install and many homeowners have successfully installed their own Skystream systems, knowledge of local zoning and building code requirements, construction techniques, as well as residential electrical systems is required for a safe installation.

Skystream dealers displaying the following insignia have completed factory triaining on the correct and safe installation of Skystream.


250 ft (75 m)

20 ft (6.5 m)

Prevailing Wind

Optimal Skystream location.

The best location to install your Skystream Hybrid 6TM may be influenced many factors. These include building code restrictions on tower heights and setbacks from property lines, the location and height of surrounding obstructions or shading, the direction and strength of prevailing winds, the length of wire runs, the tower height you’ve chosen, and the ability to fence or otherwise avoid unintended contact with the system by untrained personnel. Your dealer can help you balance these tradeoffs to find the location on your property that will best achieve your goals.

To maximize solar energy production from your system, position the tower so that the solar panels will be unshaded throughout the day through the entire year. In planning for shading, remember to account for seasonal effects of the sun rising and falling in the sky from summer to winter and changes due to leaves of deciduous plants.

To maximize wind energy production from your system, the general rule for optimum performance of the Skystream 3.7 wind turbine is that it be installed 20 feet (6.5m) above any surrounding object within a 2500 foot (75m) radius. See the figure below. TIP: See our website: www.windenergy.com for a sample inter-

connection agreement that may be used by a utility that has yet to establish a program.

Local Requirements

Building codes and installation regulations may vary greatly depending upon country, state, county, city, and local jurisdictions. Be sure to obtain all required building permits BEFORE beginning installation. Make sure you understand all inspection and installation requirements. Many locations may require installation by a licensed professional to meet building code requirements or to qualify for rebate incentives.

Utility Requirements

Be sure to contact your local electric utility company prior to installation. Many utility companies will require an “Interconnection Agreement” prior to installation. Some utilities may also require installation of a separate power meter for Skystream Hybrid 6TM.

HOW TO START ANd STOp YOUR SkYSTREAm HYBRId 6Tm

You need to take two independent actions to fully start or stop your Skystream Hybrid 6TM solar tracker system. Note, see your Skystream 3.7 Owner’s Manual concerning how to start and stop your Skystream 3.7 wind turbine.

1. Starting and Stopping Solar Panel TrackingTake these actions to start solar tracking by the solar tracker array:

a. Confirm that the controller unit is connected to one solar panel and micro-inverter.

b. Turn the switch on the controller unit to the “on” position (see Figure 1).

Once turned on, capacitors within the controller will begin to charge using energy produced by the solar panel. Once the controller senses that suf-ficient energy has been stored, the tracker will automatically begin to track the sun. Note, if you turn on tracking at night, tracking won’t begin until daytime when solar energy becomes available to power the unit.

Figure 1: Controller On/Off Switch

To turn off tracking, turn the switch on the controller unit to the “off” posi-tion (see Figure 1).

Note, turning the tracking function on or off has no impact on the function of the Skystream 3.7 wind turbine.

2. Connecting Hybrid 6Tm to the Electric grid

In order to benefit from the electric energy generated by the solar panels, the output of the solar panels must be connected to the electric grid. If the outputs of the solar panels and wind turbine have been combined, the same action will serve to turn on your Skystream 3.7 wind turbine. See your Skystream 3.7 Owner’s Manual for a more complete description of how to start and stop your turbine.

a. To connect your Hybrid 6TM system to the grid, turn to “on” the circuit breaker at the electrical utility panel where your Skystream Hybrid 6TM system is connected to the grid. If, as recommended, your installation also includes a second electrical disconnect within sight of the tower which holds the turbine and solar tracker, you will also need to turn that disconnect to the “on” position to complete the circuit to the grid.

b. To disconnect your Hybrid 6TM system from the grid, turn to “off” the circuit breaker at your electric utility panel. Or, turn to “off” the second electrical disconnect. Turning off either will interrupt the circuit and prevent the Hybrid 6TM from delivering energy to the grid. If the outputs of the solar panels and wind turbine have been combined, this same action will also serve to turn off your Skystream 3.7 wind turbine.

“ATTENTION” labels, depicted below, are provided to indicate the location(s) of the AC power disconnect switch(es) or circuit breaker(s). Apply the labels in prominent locations where they will be seen by opera-tors or service personnel.


WHAT TO EXpECT fROm YOUR SkYSTREAm HYBRId 6Tm – OpERATINg CHARACTERISTICS

You will quickly become familiar with the daily operating cycle of the track-ing solar array of your Hybrid 6TM system, which is described below. Any deviations from normal behavior should be investigated with the help of your dealer. For a description of operating characteristics of your Skystream 3.7 wind turbine, please see your Skystream 3.7 Owner’s Manual.

daytime Behavior

As the end of the night, your tracker will be parked in a south facing posi-tion. Once the sun rises in the east, the solar panel connected with the controller will begin to charge the controller. Once the controller voltage has risen and sufficient energy has been stored, the controller will auto-matically turn on and acquire a GPS signal. The controller unit will then wait until the next ten minute mark from the GPS, then activate the motor and chain drive to move the solar panels to face the sun.

Thereafter, through the course of the day, the panels will move automati-cally every ten minutes in order to track the sun.

As the sun descends in the west at the end of the day, energy production decreases and controller voltage will drop. Once controller voltage drops to a “go-home” level, the tracker will automatically move to a south facing position and stay there until morning.

SAfETY WARNINg: THE TRACkER mOVES UNEXpECTEdLY ANd WITHOUT WARNINg. To avoid injury to people or damage to equipment, people and equipment and all other obstructions must be kept clear of the tracking solar array at all times, including the chain drive and pinion gear at the bottom of the controller.

Nighttime Behavior

In response to decreasing energy production and a drop in controller volt-age at the end of the day, the controller will automatically move the solar array to a south facing position. The array will remain parked in that posi-tion overnight. Once energy production resumes in the morning and the controller voltage rises, the controller will “wake up” and begin its daytime cycle of tracking actions at 10 minute intervals.


WHAT TO EXpECT fROm YOUR SkYSTREAm HYBRId 6Tm – ENERgY pROdUCTION

Benefits of Solar Tracking and Hybrids

Your Skystream Hybrid 6™ is the most advanced hybrid solar and wind energy solution available. No other product combines solar and wind power in one package with a shared footprint. This means that your sys-tem uses minimal space while providing the energy output of a high per-formance wind turbine plus that of high efficiency tracking solar panels. The latter provide up to 40% more energy than comparable fixed solar systems.

Traditional “fixed” solar panel mounting systems don’t compensate for the changing location of the sun throughout the day. As a result, there is only one instant in any given day when a fixed solar panel is perfectly perpen-dicular to the sun, achieving maximum energy capture. At all other times of the day, the energy capture is diminished due to a less optimal sun angle. The Skystream Hybrid 6TM tracking system overcomes this short-coming by tracking the sun as it passes across the sky.

The extent to which your solar tracker increases solar energy production relative to a fixed system depends on factors including latitude, seasonal cloud coverage, and weather patterns. In general, customers can expect an improvement between 25% and 40% when compared to a fixed solar mounting system. For example, the Skystream Hybrid 6TM tracker is fore-cast to increase solar energy capture by 26% in Miami, Florida when com-pared with a fixed mount system, whereas the improvement in Bismarck, North Dakota is projected to be 34%.

Installing a hybrid system as opposed to a wind or solar-only system gives you the added benefit of more consistent energy production throughout the year. In most locations, the solar and wind resources are complemen-tary; that is, when the sun isn’t shining, it tends to be windy, and when the sun is shining, it tends to be calm. Figure 1 illustrates this phenomenon at a location in Rochester, New York. Notice that solar and wind energy pro-duction vary widely throughout the year while the sum of the two is more consistent (smoothed).

Figure 1: Complementary wind and solar energy production

preparing Your monthly forecast

To develop a monthly energy forecast for your system, we recommend you visit and use SitelookTM, Southwest Windpower’s proprietary on-line esti-mator available at http://www.windenergy.com/sitelook/consumerTB.html. The software has built-in climate databases which are used to account for seasonal shifts in solar and wind resources. It also accounts for elevation, seasonal temperature fluctuations, and product specifications. SitelookTM will determine your expected electricity bill savings and provide a detailed report.

It is important to understand that your modeled energy forecast represents an expected average result. Just as rain varies from year to year, so will your wind and solar results. Wind is especially variable and your Skystream 3.7 Owner’s Manual provides a table of environmental factors affecting your energy output from wind. Your solar output will vary, too, depending on variations in cloud cover, temperature, and airborne or panel dust. As a result, annual variations in your total energy capture of +/- 15% or more are to be expected.


Your Enphase EnvoyTm Energy Reports

After you have used Sitelook™ to create your solar energy forecast, you can use your Enphase Envoy™ account to track your actual solar produc-tion. Each of the solar panels on your Skystream Hybrid 6™ is equipped with its own Enphase™ inverter. Through your online Enphase Envoy™ account, you can observe the real-time performance of each of your solar panels. The following image depicts the real-time performance of a Skystream Hybrid 6™ installed at Southwest Windpower’s home office.

Figure 2: Envoy solar performance dashboard

The above image indicates the individual solar panels are all function-ing properly as they all show similar solar production (approximately 350 Watt-hours each so far for the day). If one panel were producing sig-nificantly less than the others, this might indicate shading of that panel. Alternatively, something may be wrong, in which case you should contact your dealer.

In addition to real-time performance results, your Envoy™ account provides your historical energy production from month to month and year to year. This will allow you to compare Sitelook’s predicted energy production with your actual production. The following figure, from a Skystream Hybrid 6TM system at Southwest Windpower’s home office, shows an example of the information contained in Envoy’s monthly report.

Figure 3: Envoy Energy Summary

As you compare your actual production with the projections from Sitelook™, remember that similar to rain, your actual yearly energy produc-tion can easily fluctuate by +/- 15% or more from your forecast of aver-age results. This is due to normal fluctuation in wind and solar resources from year to year as well as the fact that the Sitelook model used to create the forecast may not perfectly match the characteristics of your particular installation.

Activating Your Enphase EnvoyTm Account

Your Enphase EnvoyTM account is a vital tool for monitoring performance of your Hybrid 6TM system. Your system installer should activate your Enpahse EnvoyTM account at the time of installation. Please consult your installer and applicable Enpahse EnvoyTM manuals concerning initiation and use of the service.


SERVICE mAINTENANCE ANd INSpECTIONS

Your Skystream Hybrid 6TM turbine, solar tracker, and tower system should be serviced only by qualified technicians who are trained to perform the service. Under no circumstances should untrained personnel be allowed to perform service or repairs.

If service is required, please contact your dealer. If a dealer is not avail-able, contact Southwest Windpower Technical Services for assistance.

These Maintenance and Inspections Instructions pertain to the Skystream Hybrid 6TM solar tracker mechanism and solar panel array. Please see the Skystream 3.7 Owner’s Manual for Maintenance and Inspections instruc-tions relating to your Skystream 3.7 wind turbine.

Cleaning Solar Panels:

To maintain optimum performance, it is important that the glass covers on all solar panels are kept clean to enable undiminished transmission of light to the underlying solar cells. As a result, check regularly for any accumu-lation of dirt or dust. When required, spray the panels with low pressure water to clean or follow any specific instructions provided by the solar panel manufacturer. The required cleaning frequency depends on local conditions. Do not use equipment or chemicals that might scratch or cloud the cover glass.

Snow or ice on solar panels will also diminish their performance. However, snow or ice should only be removed manually if it can be done without damaging the glass in any way. It is preferable to let snow and ice disap-pear naturally. Follow any specific instructions provided by your solar panel manufacturer.

Scheduled Maintenance and Inspections

It is important to conduct periodic inspections of your solar tracker mecha-nism and solar panel array to ensure that all parts are performing as intended. Southwest Windpower recommends a regular program of major and minor inspections and recording results in a Logbook as described below. Major inspections are performed by trained technicians and minor inspections are performed visually by the owner.

Table 2: Skystream Hybrid 6Tm Solar Tracker System Logbook


ENd Of dESIgN LIfE – 20 YEARS

Your Skystream Hybrid 6TM turbine, solar tracker, and tower system is designed for twenty (20) year life in locations with IEC Class II winds according to the IEC 61400-2 “Design Requirements for Small Wind Turbines.” This corresponds to locations with average wind speeds of 19 miles per hour (8.5 m/s) which are extremely windy sites.

Actions to be taken after 20 years of operation are as follows:

1. Schedule a major inspection of the complete turbine, solar tracker, and tower system by a trained technician. This includes thorough internal and external reviews of the turbine and solar tracker mechanisms, checking the condition of all moving and electrical parts. It also includes inspecting the tower, foundation, wiring, and grounding rods or cables for any signs of corrosion, cracking, or excessive wear. All elements showing evidence of excessive wear, fatigue, or corrosion should be repaired or replaced. In addition, all fasteners should be re-torqued to the correct values before returning those elements to service.

2. If it is determined that it is safe to continue operating the turbine, please see your Skystream 3.7 Owner’s Manual concerning the man-datory replacement of all turbine blades as a balanced set.

3. If it is decided to take any elements of the system out of opera-tion, including turbine or solar tracker mechanism, then dispose of those elements according to the section of this manual “Disposal of Skystream Hybrid 6TM.” Please also read and comply with any specific disposal instructions provided in Enphase or solar panel manufactur-er’s Owner’s Manuals concerning disposal of those components.

fREQUENTLY ASkEd QUESTIONS

1. How long should it take my unit to begin tracking at the beginning of the day?

It depends on the amount of sun that is present on the solar panels. With full sunlight, it should take approximately 15 minutes.

2. How do I stop the solar tracker from providing power to the grid?

Turn to “off” the circuit breaker at the electric utility panel where your Hybrid 6TM is connected to the grid. Or, if equipped, turn to “off” the secondary electrical disconnect within sight of the tower. For additional instructions, see the section of this manual “How to Start and Stop Your Skystream Hybrid 6TM.” Note, depending on your system wiring, this action may also turn off your Skystream 3.7TM turbine.

3. How do I stop the sun tracker from tracking the sun?

Turn to “off” the switch on the controller. For additional instructions, see the section of this manual “How to Start and Stop Your Skystream Hybrid 6TM.”

4. What happens if I lose utility power?

The unit will continue to track the sun but no power will be delivered to the grid. This is in compliance with electric utility regulations.

5. Should I clean dust, dirt, snow or ice from the glass panel covers?

Clear panels allow for greater energy capture but they must be cleaned in a safe manner that will not scratch, cloud, or break the glass. We recom-mend removing dust or dirt with a low pressure water spray. It is prefer-able to let snow and ice disappear naturally. Contact your solar panel manufacturer for specific recommendations for your panels.

WARRANTY gUIdE fOR YOUR SkYSTREAm HYBRId 6Tm


WINd TURBINE ANd SOLAR TRACkER mECHANISm WARRANTY AgREEmENT

Hardware WarrantySouthwest Windpower, Inc., (“Southwest Windpower”) will repair or replace free ofcharge any part or parts of the Southwest Windpower Skystream 3.7® wind generator or solar tracker mechanism (solar tracker mechanism as used in this Warranty does not include solar panels, solar panel inverters, or associated wiring) determined by Southwest Windpower to be defective in materials and/or workmanship under normal authorized use consistent with product instructions for a period of five years from the date the original purchaser (“Customer”) receives the wind generator and solar tracker mechanism (“Start Date”). This warranty extends only to the original purchaser. The Customer’s sole and exclusive remedy and the entire liability of Southwest Windpower, its suppliers and affiliates under the warranty is, at Southwest Windpower’s option, either (i) to replace the wind generator or solar tracker mechanism with a new or reconditioned wind generator or solar tracker mechanism, (ii) to correct the reported problem, or (iii) to refund the purchase price of the wind generator or solar tracker mechanism. Repaired or replaced products are warranted for the remainder of the original warranty period.

RestrictionsProblems with the wind generator or solar tracker mechanism products can be due to improper use, maintenance, non-Southwest Windpower additions or modifications or other problems not due to defects in Southwest Windpower’s workmanship or materials. No warranty will apply if the wind generator or solar tracker mechanism (i) has been altered or modified except by Southwest Windpower, (ii) has not been installed, operated, repaired, or maintained in accordance with instructions supplied by Southwest Windpower, (iii) has been exposed to winds exceeding 140 mph (63 m/s), or (iv) has been subjected to abnormal physical, thermal or electrical stress, misuse, negligence, or accident. If Southwest Windpower’s repair facility determines that the problem with the wind generator or solar tracker mechanism is not due to a defect in Southwest Windpower’s workmanship or materials, then the party requesting warrantyservice will be responsible for the costs of all necessary repairs and expenses incurred by Southwest Windpower.

Warranty Claims and Return ProceduresIn order to be eligible for service under this Limited Warranty, the Customer MUST return the warranty registration document included with this Limited Warranty within sixty (60) days of the start of the Warranty Period. Alternatively, customers may register their system on line through www.windenergy.com.

Customers experiencing a problem with their Skystream Hybrid 6TM system should first contact an authorized Southwest Windpower Skystream dealer in an attempt to diagnose and resolve the issue. If it is confirmed that there may be a

warrantable issue, the customer may request the assistance of the authorized dealer or notify Southwest Windpower Technical Services directly in order to start the claims process with Southwest Windpower. Claims notification may be made by phone or in writing. Whether made by the dealer or by the Customer, the warranty claims notification must include a description of the alleged defect, the physical location of the system, relevant serial numbers for the system, the manner in which the system was used, the original purchase date, and the name, address, and phone number of the party requesting warranty service. All claims for defects shall be deemed waived unless made within thirty (30) days following discovery of the defect.

In response to such notification, within three (3) business days, at Southwest Windpower’s discretion, Southwest Windpower will take action to attempt to confirm whether a warrantable issue exists and to resolve the issue, either through an exchange of information between the requesting Customer and Southwest Windpower, or by assigning an authorized Southwest Windpower representative to inspect the system in person to evaluate the issue and implement repairs, or by issuing a Return Authorization (“RA”) to the Customer under which the Customer may return the applicable equipment to Southwest Windpower for inspection and repair. If Southwest Windpower chooses to send a representative, the Customer must make the applicable equipment accessible for inspection and servicing by the representative at reasonable times.

If Southwest Windpower issues an RA for return of the equipment, such equipment shall be shipped at the expense and risk of the party requesting warranty service, including but not limited to proper packaging of the equipment. If Customer no longer has the original packaging, Southwest Windpower may send packaging materials to the Customer. Southwest Windpower will be under no obligation to accept any returned equipment that does not have a valid RA number attached or plainly visible. Customer’s failure to return the agreed equipment within thirty (30) days of Southwest Windpower’s issuance of an RA number may result in cancellation of the RA.

Southwest Windpower will use all reasonable efforts within ten (10) business days of receipt of the alleged defective equipment to repair or replace such equipment. If upon inspection, the warranty claim is found invalid for any reason, Customer may be charged at Southwest Windpower’s or the authorized representative’s then current rate for repair or inspection services and return shipping expenses. In such event, the Customer will be informed of the repair charges, and upon Customer approval of such charges, the Customer will be charged for the repairs and return shipping. If the Customer refuses to approve repair charges for any equipment for which a warranty claim is invalid, return shipping charges may apply. Customer property remaining at Southwest Windpower for more than thirty (30) days without required Customer approval of return shipping charges becomes the property of Southwest Windpower.

For equipment repaired under warranty by Southwest Windpower, all parts that Southwest Windpower replaces shall become property of Southwest Windpower on the date that Southwest Windpower ships the repaired equipment back to the

Skystream Hybrid 6Tm Limited 5-Year Warranty


customer. Equipment repaired or exchanged by Southwest Windpower under warranty is warranted for the remainder of the original Warranty Period.
